Some of us use our own custom/creative callsigns when flying throughout the servers. I’m curious to know the meaning behind some of them! I’ll start with mine.
C-FTDG: Basically, TDG is the initials for the Canadian Rock band, Three Days Grace. I’m a huge metalhead and TDG is one of my favorite bands! C(Canadian initial) and F(Fan).
You may comment/post below about your custom/personal callsigns! 
Mine is G-MPIE
G - as it’s a UK registration
MPIE - is for my name Mark Pierce
Mine is ST-PFM
It mostly comes from my former username (NonSTopPopFM)
But even after changing it, I’ve grown to this callsign and don’t feel like changing it
I use M-ORTY (for obvious reasons).
Mine is G-AZER or CAP 37 (CAP-civil Air patrol 37-my squadrons radio callsign is Red Dragon 37)
I used to run A-WU but since the callsign change made this impossible I run VP-AWU as well because VP sounds cool
Mine is TF-ICE.
Yes, it’s the icelandair registration on the max but it’s pretty obvious why I chose it!
TF (Icelandic Prefix)
ICE (short for Icey).
All things Ice basically!
S2-AFF
S2 for my ethnicity. The rest is self explanatory.
AP-TPT. Unlike comments and descriptions above I lack creativity and originality 
Mine is G-BBAX
G: UK prefix
BBA: BennyBoy_Alpha
X: cool letter
You should do VP-UWU
Why did I know someone was going to say that…
I use some airline or military prefix, but then my number is always 623, as my birthday is June 23
Is this even a possible thing? I feel like my VP-AWU is VP-A followed by WU not VP followed by AWU. Can’t check, no sub.
@Humanguy summin
Oh ya your name has the 3 Letters
M-DELA, sounds cool and obvs short for my name
Hihihihihihihihih
I-ARLN, because I am arlin1
UndrewWu VP-UWU lol just joking
